Growth performance of male Zaraibi goats fed Teosinte forage in rations differing in roughage: concentrate ratio
Abstract: This work was carried out on male Zaraibi goats to investigate the effect of using Teosinte forage in two roughage: concentrate (R/C) ratio (40:60 and 60:40) on growth performance, feed conversion and some blood constituents as well as economical efficiency. Eighteen male Zaraibi goats were divided into three equal groups (BH-40G, T-40G and T-60G) and fed according to NRC (1981) allowances:
BH-40G fed 40 berseem hay (BH): 60 concentrate feed mixture (CFM), T-4OG received 40 Teosinte: 60 CFM and T-60G nourished 60 Teosinte: 40 CFM.
The data indicated that the digestibility of most nutrients of T -40G was significantly higher compared with BH-40G and T-6OG. Thus, the TD*9N and DCP values were significantly better with T -40G (69.06 and 10.25, respectively) than BH40G (65.27 and 10.05, respectively). The lowest values (P<0.05) of TDN (61.40) and DCP (8.51) were recorded with T -6OG. Daily body gain (DBG) was improved with BH40G and T-40G by 10.93 and 18.79 %, respectively compared with T-60G. Moreover, the DBG was increased by 9.68 % in T-40G than BH-4OG. The feed conversion efficiency based on DM was better with T -4OG followed BH-40G and lastly T -60G. The same trend was observed with feed conversion based on TDN and recorded 10.20, 9.76 and 10.50 for BH-40G, T -40G and T-60G, respectively. Using Teosinte forage in goat rations reduced feed cost/kg body weight gain from 13.93 LE in BH40G to 11.90 and 11.72 LE in T-40G and T-6OG, respectively. Therefore, the economic efficiency was higher with T-40G (1.68) and T-6OG (1.71) compared with BH-40G (1.43). The economic efficiency was improved with the two Teosinte rations (T-40G and T-6OG) by 17.5 and 19.6%, respectively compared with BH-40G (BH ration). Accordingly, feeding Teosinte at 40% instead of clover hay + 60 CFM level has better impact on growing kids either for growth rate or feed conversion efficiency and economic values.
